3M™ Hard Hat H 700 Series with 4 Point Ratchet Suspension and UVicator™ Sensor is comfortable, tough and lightweight protective headgear that helps protect the top of the head due to the potential hazard of small falling objects or exposed fixed objects that may be bumped into. The UVicator™ sensor changes color as the hard hat is exposed to UV light. The sun’s UV rays can cause a hard hat shell to become brittle and compromise its ability to protect the wearer. With the UVicator™ sensor, the hard hat should be replaced when the sun smart sensor changes from red to white. A 4 point ratchet suspension adjusts easily to allow for a customized height and fit that best suits the individual who wears the hard hat. The ratchet system allows tightening or loosening the fit without taking the hard hat off. Workers wearing this hard hat will also appreciate its low profile design and balanced fit, which provide for a more comfortable and less obtrusive feel. A short brim allows for upward visibility, a feature that can enhance both safety and productivity. The soft brow pad cushions the forehead and is removable for easy replacement. For added versatility, the hard hat features accessory slots to accommodate 3M’s cap mounted ear muffs, headgear, faceshields, and welding helmets (all sold separately). A hardhat is commonly worn in these industries: heavy and light industrial, construction, oil and gas, road work, forestry, and mining. This hard hat meets requirements of ANSI/ISEA Z89.1 2014 Type I, Class G and E. The hat may be worn in either the forward or reverse donning position. Hat weighs 12.8 ounces. The rigid shell of the 3M™ Hard Hat H 700 Series helps reduce chances of injury by deflecting small falling objects from striking the head of the person who wears this protective headgear. The hard hat also helps protect from injuries due to bumping into stationary objects such as pipes, rods, shafts, construction timbers, branches, or exposed electrical conductors.
